When the 7th district looks like a fish having sex with a cat (they aren't even connected, mind you), it's a problem. When a tilt D state has a 2:1 GOP advantage in Congress, it's a problem.
I've thought about this and after you remove the 2 or 3 districts in Philadelphia and the Pittsburgh district, there really isn't much left for Dems to have too many more districts. I mean those districts are like beteen 90-10 to 75-25 for the Dems while the GOP ones are like 60-40 (on average), therefore, the numbers seem more out of whack than they are for Congressional reistricting. What map would you propose that is actually clean?
